Specification of Letters Patent.

Patented Oct. 19, 1909.

Application filed Jane 23, 1909. Serial No. 503,836.

To all whom it may concern:

Be it known that I, FRANK E. VANDER- COOK, a citizen of the United States, residing at \Vaterbury, in the county of New Haven and State of Connecticut, have invented an Improvement in Rotary Vire- Straighteners, of which the following is a specification.

My invention relates to a rotary wire straightener adapted to have passed or drawn through it a length of wire from a reel; the wire being received therefrom as curved or bent and delivered therefrom in a perfectly straightened condition.

My invention aims to produce a simple inexpensive and easily adjustable wire straightener adapted for rotation by a suitable device which shall receive and hold the wire straightener and impart thereto a high rotation.

In the device of my invention, I provide a slotted tubular-ended spindle Preferably with an imperforate center. The tubular ends of the spindle receive bushings suitably held thereto and the bushings movable endwise and revoluble for adjustment. A collar surrounds the central portion of the spindle and the same is peripherally curved; the curves being in the line of the spindle axis. The collar is held to the spindle in any desired position and in connection with this structure I prefer to employ a bracket which carries a hollow arbor revolved at a high speed by a pulley and belt or equivalent means.

The wire to be straightened is fed from a reel through this hollow arbor through one bushing and the slot at one end of the spindle out of the slot and over the collar through one of the grooves thereof, down through the other slot of the spindle and through the other bushing and away, straightened for use.

In the drawing, Figure 1 represents the device of my invention as rotatably mounted and connected to a hollow arbor supported by a suitable bracket and provided with a pulley and other parts. Fig. 2 is a plan of the device of my invention alone, and Fig.

3 is a cross section at a2, 00, through the spindle and a side elevation of the peripherally grooved collar.

The slotted tubular-ended spindle is shown at a, a being the slots at opposite sides of a preferably imperforate center.

These slots run lengthwise'of the spindle and merge. into the tubular ends which are adapted to receive the bushings 7) 5 These bushings fit snugly, they are tubular and are held in position by the set-screws 2. The apertured ends of the bushings b I) are made conical or flaring and said bushings are movable end-wise and are'revoluble in the spindle, thus. providing not only an adjust in'ent as may be required for wires of slightly different thickness, but a rotation for wear; theset-screws 2' being suflicient to hold them to the spindle in a fixed relation.

0 represents a collar surrounding the spindlc at about the center and provided. witha set-screw 3 for fixing thesame in its relation to the spindle. This collar is provided with peripheral grooves c which run across the face or periphery of the collar and in line with the axis of the spindle. These grooves may be of slightly different sizes to receive wires that vary in diameter, and the object of turning the collar is to be able to bring into line with the slots a of the spindle any groove of the collar that may fit the wire, and especially a groove that is not seriously worn. The bases of these grooves are preferably convex to provide for the drawing of the wire over the face of the collar as shown in Fig. 1. I have shown in Fig. 1 a device adapted to have the spindle connected thereto for its rotation and support. This device comprises a bracket 6 in which is journaled a hollow arbor f carrying a pulley 7 between the parts of the bracket; the pulley being adapted for a belt to provide for the rotation thereof and also the hollow spindle and the wire straightening device of my invention. This bracket structure is advantageously provided with oil cups 4 5 for lubricating the hollow arbor f, with an oil receptacle 6 for coating the wire d, and with bushings 7 through the tubular body of which the wire passes from the reel to the straightening device.

From the drawing it will be apparent that the rotary wire straightener at one end is connected by the projecting bushing to the hollow arbor f; that is to say, the projecting bushing passes into the hollow arbor and is connected in a firm relation thereto by a setscrew 8 and the parts should fit so snugly that the wire straightener device of my invention should form a perfect axial prolongation, or in other words, be exactly in the axial line of the hollow arbor so that the same will rotate truly with the arbor.

The wire after passing through the bushings 7 and the hollow arbor 7 passes through the bushing 79 into and out of a slot of the spindle, over the collar 0 and through one of the grooves thereof, then down into the other slot of the spindle and through the bushing b and away to the machine employed for drawing the wire through.

It is quite essential in this operation that the wire should be coated with oil received from the receptacle 6 and that therefrom the parts in contact with the wire should be fully lubricated for the reason that while the spindle and its collar 0 turn at a very high speed, the wire (Z does not turn but is straightened by the turning movement of the spindle and collar bending the wire back and forth as it is drawn through. In this operation the bushings b play an important part in straightening the wire.

lVhile I have herein shown and described a bracket, a hollow arbor and pulley, etc., for supporting, connecting with and rotating the spindle and its collar, I do not limit myself to the precise character and details of construction of these parts, as the same may be modified without departing from the spirit of my invention.

I claim as my invention:

1. A rotary wire straightener comprising a slotted tubular-ended spindle adapted to be, rotated, a central collar peripherally grooved in the line of the spindle and over which the wire draws as it is drawn through the spindle of the straightener.

2. A rotary wire straightener comprising a slotted tubular-ended spindle adapted to be rotated, a central revoluble collar peripherally grooved in the line of the spindle and over which the wire draws as it is drawn through the spindle of the straightener, and means for securing the collar in a fixed relation to the spindle.

3. A rotary wire straightener comprising a slotted spindle apertured at its respective ends, tubular bushings fitting the ends of the spindle and means for securing the bushings adjustably in position, a collar surrounding the spindle at about the center thereof and provided with peripheral grooves in the line of the spindle axis, the spindle at one end being adapted to be engaged by a suitable rotary device.

4. A rotary wire straightener comprising a spindle, tubular-ended and slotted between the tubular ends and the center which is left imperforate, bushings fitting the tubular ends of the spindle adjustable therein and means for clamping the same in position, a collar surrounding the central imperforate portion of the spindle and the collar peripherally grooved in a line of the spindle axis and revoluble, means for clamping the collar in position on the spindle, and a revoluble device receiving the wire straightener at one end, a support for the revoluble device and means for turning the same.

A rotary wire straightener comprising a slotted tubular-ended spindle, bushings litting the tubular ends of the spindle and the bushings provided with longitudinal or axial openings with flaring ends, means for securing the bushings in an adjustable relation to the spindle, a collar surrounding the spindle at about the center thereof and means for clamping the same in position, the collar being peripherally grooved atintervals in its circumference and the grooves in the line of the spindle axis, and the bases of the rooves curved to conform to the line of direction taken through the device by the wire being straightened, and a suitable supportfor the wire straightener and with which it is rotated.

6. A rotary wire straightener comprising a slotted tubular-ended spindle, bushings fitting the tubular ends of the spindle and the bushings provided with longitudinal or axial openings with flaring ends, means for securing the bushings in an adjustable relation to the spindle, a collar surrounding the spindle at about the center thereof, means for clamping the same in position, the collar being peripherally grooved at intervals in its circumference and the grooves in the line of the spindle axis, and the bases of the grooves curved to conform to the line of direction taken through the device by the wire being straightened, a bracket, a hollow arbor journaled in the bracket and the hollow arbor at one end receiving the projecting end of one of the aforesaid bushings of the spindle, means for securing the spindle by its bushing to the hollow arbor and means for rotating the hollow arbor.
